I've decided to take on the project of re-wiring the outlets and switches in my home. As a total beginner with no prior electrical experience, this may seem daunting, but with proper planning and caution, it is possible for a dedicated DIYer to take this on. Here is my comprehensive guide to re-wiring outlets and switches as a complete novice.

Understanding Electrical Basics

Before beginning any electrical project, it's crucial to understand some fundamental concepts about how electricity works in a home. This will help me work safely and effectively.

Electricity Basics

• Electricity flows in a circuit. It needs a complete loop to flow correctly.
• Circuit breakers and fuses protect against overloads. They will trip and cut power if too much electricity flows through.
• Voltage is the "pressure" that pushes electricity through wires. Standard household voltage is 120V in the US.
• Amps (amperage) measure how much electricity is flowing. More amps means more power.
• Electricity can be dangerous if mishandled. Always exercise caution when working with household electrical.

How Switches and Outlets Work

• Switches open or close a circuit. Flipping a switch breaks or completes the loop.
• Outlets provide access to electricity. They have hot and neutral terminals to tie into.
• Both require correct wiring to integrate into the home's electrical system.

Now that I understand these basic principles, I'm ready to start my project.

Gathering the Right Materials

Re-wiring outlets and switches requires:

• Wire strippers - to strip insulation off wires
• Voltage tester - to safely check if wires are live
• Needle-nose pliers - for manipulating wires in boxes
• Wire nuts - to join copper wires together
• Electrical tape - for insulating connections
• Replacement outlets/switches - match amperage and number of poles
• Pigtails - short jumper wires to connect devices
• Wire - I'll need 12 AWG or 14 AWG copper wire for 15A/20A household circuits

I now have all the materials I need. It's time to start replacing those outdated outlets and switches!

Shutting Off Power and Removing Old Devices

Safety is paramount when working with electrical. I'll take the following steps before doing any work:

• Shut off the main breaker - This cuts power to the whole house
• Test wires with a voltmeter - Ensure power is off with a voltage tester
• Remove old outlet/switch cover plate - Take off the decorative plate
• Unscrew and remove the device - Outlets and switches are held by long screws
• Label all wires - Use masking tape to identify neutral, hot, ground, travelers, etc.

This will let me work safely on the disconnected outlets and switches. Proper labeling will help me reconnect the new devices correctly.

Installing New Outlet

Installing a new outlet is straightforward with basic wiring knowledge:

1. Secure the outlet - Screw it into the electrical box firmly
2. Connect hot wire - Identify hot wire(s) and connect to brass hot terminal
3. Connect neutral wire - Attach neutral wire to silver neutral terminal
4. Connect ground wire - Secure bare copper or green wire to green ground screw
5. Organize wires - Bundle extra wire length neatly in the box
6. Re-install cover plate - Screw decorative plate back into place

Following this simple step-by-step process will ensure proper electrical function. Take care not to over-tighten connections or allow bare wire exposure.

Installing New Switch

Installing a replacement switch also uses a basic process:

1. Secure switch - Screw the new switch firmly into the electrical box
2. Connect hot - Attach the hot input wire to the brass screw
3. Connect traveler wires - Link both traveler wires to the traveler screws
4. Connect ground wire - Secure ground wire to green ground screw
5. Organize wires neatly - Bundle extra length cleanly in box
6. Re-install cover plate - Attach decorative plate with switch face exposed

This will complete the circuit so the switch can operate properly. Follow switch manufacturer instructions closely.

Helpful Tips and Warnings

Here are some additional pointers to ensure success and safety:

• Work slowly and double check connections. Rushing leads to mistakes.
• Only work on small sections at a time. Don't open up everything at once.
• Use wire nuts to insulate connections. No exposed copper should be visible.
• Never assume wires are unlabeled. Always use a voltmeter to confirm.
• Consult an electrician if something seems overly complex or confusing.
• Call the pros for large re-wiring jobs - this guide is for simple outlet and switch replacement only.

Exercising patience and caution will go a long way for a first-timer. Even complex wiring can be broken down into manageable steps.

In Summary

While it takes research and preparation, a homeowner can absolutely re-wire outlets and switches themselves as a beginner. By:

• Understanding basic electrical principles
• Gathering the right tools and materials
• Working carefully with the power off
• Following proper wiring procedures
• Seeking help when needed

The average handyperson can upgrade their outdated outlets and switches and take pride in a job well done! With the right knowledge and safety mindset, minor household electrical projects are within reach.
